Specialized is obsessed with making the best bikes possible, so they created the S-Works Tarmac SL4 Frameset. It uses Specialized's FACT 11r-carbon in the frame and fork for phenomenal stiffness and remarkably low weight. In front, they've integrated the down-, top-, and head-tube junctions to make it supremely stiff for rocketing up climbs, diving into corners and sprinting for the line. A one-piece BB/chainstay also trims weight while improving the all-important drivetrain stiffness, proving that obsession can be a very good thing.
This frame utilizes Specialized’s advanced FACT IS (Integrated Structure) construction method. By separating the frame into four main parts — the front triangle, seat tube/bottom bracket, chainstays and seatstays — Specialized is able to optimize each carbon piece for its specific purpose and create a structure that’s incredibly light, impeccably stiff and impressively strong.
This frame’s head tube is 1 3/8 inches in diameter at the bottom and 1 1/8 inches at the top. This maximizes front-end stiffness for awesome steering precision and control, while allowing the use of standard 1 1/8-inch stems and not adding much weight.
